Permeate Spacer Module

A permeate spacer module comprising a spacer and at least one collection device, which spacer comprises of at least one inserted element and of support members selected from at least one member of the group consisting of support surface units, solid surface material(s) having perforations, porous surface material(s), composite surface material(s) having perforations or pores or combinations thereof, sandwich surface material(s) having perforations or pores, or combinations thereof, the support members being spaced apart by the at least one inserted element forming flow space, passages or flow channels between the support members and the inserted element for guiding permeates to the at least one permeate collection device connected or attached to the permeate spacer module.

A membrane system comprising a spacer and at least one collection device, which spacer comprises of at least one inserted element and of support members selected from at least one member of the group consisting of support surface units, solid surface material(s) having perforations, porous surface material(s), composite surface material(s) having perforations or pores or combinations thereof, sandwich surface material(s) having perforations or pores, or combinations thereof, the support members being spaced apart by the at least one inserted element forming flow space, passages or flow channels between the support members and the inserted element for guiding permeates to the at least one permeate collection device connected or attached to the permeate spacer module;

• and
• a permeate spacer module wherein the membrane films, leaves or sheets, are attached on both sides of the spacer.

A process for collecting permeates comprising following steps, i) contacting a membrane system to fluids, transferring permeates through a membrane;

• the membrane system having a permeate spacer module wherein the membrane films, leaves or sheets, are attached on both sides of the spacer;
• ii) creating a flow of permeates through flow space, passages or flow channels defined by the permeate spacer module;
• and iii) collecting the permeate in at least one permeate collecting device connected to the flow space, passages or the flow channels.

A membrane plant comprising a membrane system having a permeate spacer module wherein the membrane films, leaves or sheets, are attached on both sides of the spacer;

• and
• wherein the membrane plant also comprises a collection tank, or a container, or a well.

A plate and frame membrane comprising at least one membrane system having a permeate spacer module wherein the membrane films, leaves or sheets, are attached on both sides of the spacer.

A membrane bioreactor comprising at least one membrane system having a permeate spacer module wherein the membrane films, leaves or sheets, are attached on both sides of the spacer.
